Hello George,
Pro Deo 1.1 Vulcan {9i6g} might have just avoided playing 13..dxc4 in a
tournament game, but that is mainly because it overestimates Nc6 for a while. At
fifteen ply it just goes back to dxc4
After entering 1..dxc4 2.d5 Qxd5 Vulcan {9i6g} finally begins to see enough
compensation for the pawns.
